Defining Thrust Events
|Top Previous Next|
After adding a KalmanFilterOD, SquareRootInformationFilterOD, UnscentedKalmanFilterOD, or BatchLeastSquaresOD object to your Mission Plan, you can define thrust events to model during the estimation process. You can do this by double-clicking on the Orbit Determination object to edit it, and proceeding to the "Thrust Events" page (shown in the image below). FreeFlyer will show a list of all the available ImpulsiveBurn, FiniteBurn, and OutgassingEvent objects that exist in the Object Browser.
KalmanFilterOD Events To Model Page
When working with thrust event objects that have been created in FreeFlyer script, you can use the AddThrustEventToSequence method, as shown in the syntax example below:
After the thrust events have been added to the sequence, their properties can be estimated in a Batch Least Squares estimation process. See the Defining Properties to Estimate page for more information.
